How does trade liberalization affect wages? This is the first paper to consider in theory and data how the impact of final and intermediate input tariff cuts on workers’ wages varies with the global engagement of their firm. Our model predicts that a fall in output tariffs lowers wages at...

This paper reviews the new approach to international trade based on firm heterogeneity in differentiated product markets. This approach explains a variety of features exhibited in disaggregated trade data, including the higher productivity of exporters relative to non-exporters, within-industry...

This Paper analyses the effects of reducing trade costs on the location of manufacturing firms that are vertically linked and differ in factor intensities. I extend the new economic geography literature, by embedding a model with vertical linkages within a Heckscher-Ohlin framework. Firms can...

This paper develops a theory which investigates how firms' choice of corporate organization is affecting firm performance and the nature of competition in international markets. We develop a model in which firms' organisational choices determine heterogeneity across firms in size and...

We expect trade liberalization to give rise to aggregate productivity gains, as the least efficient firms are forced out, and labor is reallocated towards the best performing firms. But the positive intra-industry reallocation effects rely on the stark assumption that exporters’ superior...

This paper estimates the effects of trade liberalization on plant productivity. In contrast to previous studies, we distinguish between productivity gains arising from lower tariffs on final goods relative to those on intermediate inputs. Lower output tariffs can produce productivity gains by...

This paper reviews the empirical evidence on firm heterogeneity in international trade. A first wave of empirical findings from micro data on plants and firms proposed challenges for existing models of international trade and inspired the development of new theories emphasizing firm...

I survey the influence of Grossman and Hart's (1986) seminal paper in the field of International Trade. I discuss the implementation of the theory in open-economy environments and its implications for the international organization of production and the structure of international trade flows. I...

In this paper, we analyze the effect of reducing import tariffs on intermediate inputs and final goods on the wage skill premium within firms in Indonesia – a country with a high share of unskilled workers. We present a new finding that reducing input tariffs reduces the wage skill premium...

Empirical studies of firms within industries consistently report substantial heterogeneity in measures of performance such as size and productivity. This paper explores the consequences of joint heterogeneity on the supply side (sellers) and the demand side (buyers) in international trade using...
